Seaflex Use of Buoyancy for Jacket Installation Application Note

Safeguarding jacket installation using Seaflex buoyancy modules

In order for a crane with a single hook to be used for the upending operation, the jacket needs to be lowered in the horizontal position into the water then and then float of its own accord. Additional buoyancy is usually also fitted as a contingency to be sure that the jacket still floats even if some of the caps fail to cause the members to flood and bringing with it the risk of the jacket becoming unstable and/or sinking unless a backup is in place.

Some of the benefits of using Seaflex air-filled buoyancy units within this type of application are that it is:

  • Backed up with project engineering experience and guidance from the manufacturer, along with onsite support from a Seaflex technician if so required.
  • Fully compliant with IMCA D-016 guidance, and type-tested to prove a minimum 5:1 factor of safety.
  • Flat-packed for efficient and cost-effective transport and storage.
  • Weighing less than 1% of its uplift capacity: e.g. 5t unit less than 50kg.
  • Quick to rig, and easy to vent for ultra-safe recovery.
    Immediately available for rental or purchase from the world’s largest stock of such equipment.
  • If rented, then subject to the highest testing and re-certification standards in the industry.
